Most home roof repairs on Staten Island cost $300–$1,200. Small leak patches and missing shingles are at the low end; flashing, valleys and flat-roof seams in the middle; storm-damaged sections can reach about $3,500. A repair makes sense when the roof is under about 15 years old and the damage is in one area.

The repairs Staten Island homeowners call us for most
Leaks around chimneys
Chimney flashing is one of the most common leak points on Staten Island homes. We replace step and counter flashing instead of smearing tar over it.
Missing or damaged shingles
Nor'easters lift and tear shingles, especially on exposed homes near the water in South Beach, Midland Beach and Great Kills. We replace them and reseal the area around them.
Valleys
Where two roof slopes meet, water piles up. Worn valleys get new underlayment and metal or woven shingles.
Vents and pipe boots
Cracked rubber boots around plumbing vents are a cheap fix that prevents expensive ceiling damage.
Flat roof sections
Rear extensions, garages and attached townhouses: seams, blisters and punctures in EPDM, TPO or modified bitumen.
Gutters and drip edge
Overflowing gutters can push water under the roof edge. We fix the gutters and the edge metal together.
What makes a repair last
A repair is only as good as the diagnosis. Water often runs along rafters before it shows up on a ceiling, so the stain is rarely right under the hole. We inspect the whole roof, scan it with an infrared (thermal imaging) camera to see where hidden moisture is spreading, check the attic when we can, and photograph what we find. Then we fix the cause with proper materials: new flashing, matched shingles, sealed seams. No caulk-and-go patches.
Your questions before you call
Is it going to be expensive?
Most repairs land between $300 and $1,200, and you see the written price before we touch anything. Our roof leak repair cost guide breaks down the numbers.
Will insurance cover it?
Sudden storm, wind or tree damage often is covered. Wear and age usually aren't. Either way, we give you photos and a written estimate.
Will you leave a mess?
No. We protect your yard and shrubs, take every scrap with us and sweep for nails.
Can I trust you on my roof?

When we'll tell you not to repair
If your roof is over 20 years old, leaks in several places, has a soft or sagging deck, or has already been patched more than once, more repairs usually mean paying twice. In that case we show you the photos and give you a roof replacement price next to the repair price, so you can decide with real numbers. The roof replacement cost guide shows what a full roof usually runs.

What Staten Island customers say
“Called them up thinking I needed a new roof and gutters. They stopped by the same day, gave me an assessment of everything and it turns out the roof was repairable. They didn't try to pressure me into any unnecessary work. Just simply he gave me a couple of prices depending on what I decided to do. They were able to schedule the job quickly for a few days later and by the middle of the afternoon everything was done and it looks great!”
“I called for an estimate for a new roof. The price they quoted was way below two other estimates I received. I was also told that it would take 1-2 days to complete. Everything Alter Phase Contracting Inc promised was delivered. They gladly supplied me with their licensing and insurance information. The warranty is printed on my…”
“Just WOW! I expected that this would take several days, they got my new roof done in just 1 day. The guys did a thorough job, from set up to clean up. The price quoted was the price I paid, no gimmicks. True Staten Islanders. My roof looks great, couldn't be more happier. Would recommend to anyone who asks.”
“Marke and his team did an excellent job on replacing my roof! He and his brother came to my house, climbed up the roof to investigate the condition unlike other contractors which were only using a drone to take pictures. He gave me honest opinion and options for replacing my roof. Great communication and very easy to work with during…”
“10/10 would recommend! This is the second time I've used this company, and they've been excellent both times. The first time was a few years ago for a full shingle replacement. Most recently, I called them back to repair my flat roof and gutter system after a rough winter caused pooling and a leak. They came out the very next day to…”

The new roof has withstood several heavy rainstorms without any leaks. They are very respectful to come back inspected whole roof to make sure no any…”

(929) 370-1552Residential roof repair: common questions
How do you find where a roof leak is coming from?
We start with an infrared (thermal imaging) camera. Wet insulation, decking and drywall hold heat differently from dry material, so hidden moisture shows up on the screen even when nothing is visible yet. That shows us where water is spreading inside the roof, often several feet from the stain on your ceiling. Then we confirm the entry point on the roof, photograph it and fix the source, not the symptom.
How much does a home roof repair cost on Staten Island?
Most repairs cost $300 to $1,200. A minor leak patch is $300 to $650, shingle repairs $350 to $800 and flashing replacement $450 to $900. You get an exact written price after a free inspection.
Can you match my existing shingles?
Usually closely. We match brand, style and color where the product is still made. On older roofs the new shingles can look a little brighter at first, which typically evens out as they weather.
How long does a typical home roof repair take?
Most residential repairs are finished in a few hours to one day.
Do I need to be home during the repair?
Not for most outside repairs. If the leak affected the inside of the house, we'll want to check the attic or ceiling before and after.
Is a roof repair worth it on an old roof?
If the roof is over 20 years old and leaking in more than one place, repairs often turn into a cycle. We'll tell you honestly and give you both a repair price and a replacement price.
